  • You can view data for up to the last 12 months, forecast how much you’re likely to spend for the next three months and get recommendations on what Reserved Instances to purchase.

    • The Monthly Costs by Linked Account report lets you view the distribution of costs across your organization.
    • The Monthly Running Costs report gives you an overview of all of your running costs over the past three months and provides forecasted numbers for the coming month with a corresponding confidence interval.

    • How close your plan is to your budgeted amount or to the free tier limits
    • Your usage to date, including how much you have used of your Reserved Instances and purchased Savings Plans.
    • Your current estimated charges from AWS and how much your predicted usage will incur in charges by the end of the month
